Nonprofit Credit Card Processing: Fees, Rates, Receipts

How a donation card payment is priced

When a donor pays by card, three layers of cost come out of the gift. Interchange goes to the donor's card-issuing bank and is set by the card network's published schedule. Network assessment fees go to Visa, Mastercard and the other brands. The processor's markup covers the acquiring bank, the gateway and whoever sold you the account. Flat-rate providers bundle all three into one price, such as a percentage plus a fixed cents amount. Interchange-plus pricing passes interchange and assessments through at cost and shows the markup separately. For a nonprofit, the distinction matters because a lower charity interchange rate only reduces your bill if your pricing model actually passes it through. On a flat rate, the provider keeps the difference. On interchange-plus, you see it on the statement. CELER Merchants is an independent agent, not a processor, so the practical step we recommend is the same whichever provider you use: ask for a written breakdown of interchange, assessments and markup before you sign.

Charity interchange rates: what Visa publishes

Visa's US interchange schedule, Visa USA Interchange Reimbursement Fees dated 18 April 2026 with rates effective April 18, 2026, lists Charity fee programs in its consumer credit tables for both card-present and card-not-present transactions. Both lines show 1.35% + $0.05, and that figure is the same across every consumer credit product column in the table, from Visa Infinite to Traditional. By comparison, the same document lists Non-Qualified Consumer Credit at 3.15% + $0.10. The schedule also notes that the Charity 1 card-not-present program is excluded from most card-not-present incentives, although Charity 1 transactions authenticated through Visa's Digital Commerce Authentication Program qualify for the Type 1 incentive of -0.05%. We did not find a charity-specific line in the debit card tables of the same document, so debit donations follow the standard debit rates. The fee schedule itself does not spell out the eligibility test. Qualification depends on how your acquirer sets up the account, including your merchant category and the documentation it asks for, so ask your processor directly whether your account is coded to receive the charity program and request proof on a statement. Mastercard also publishes US interchange rates, but its published schedule is not retrievable from a plain request, so we have not quoted a Mastercard figure here. If your donations skew to Mastercard, ask your acquirer to show you the Mastercard interchange lines your account is actually clearing in, on a statement.

Published nonprofit pricing from common providers

Few providers publish a nonprofit rate, and those that do attach conditions. PayPal's US fees page lists charity transactions at 1.99% plus a fixed fee, with an extra 1.50% for international charity transactions, and states that charity rates are subject to eligibility, application and pre-approval. Stripe's support page describes a nonprofit fee discount for registered nonprofits in eligible countries, including the United States and Canada, where at least 80% of Stripe payment volume comes from tax-deductible donations, but it does not publish the discounted rate; you apply through a request form. Square's nonprofit page lists its standard 2.6% + 15 cents for in-person card payments and 3.3% + 30 cents for invoices, and we found no nonprofit-specific rate on it. Donation platforms add another layer. Donorbox's Standard plan lists a 2.95% platform fee plus payment processing fees. Givebutter lists 0% platform fees when donor tips are enabled, or a 3% platform fee plus 2.9% + $0.30 card processing when tips are disabled. Zeffy states it charges nonprofits no platform or card fees and is funded by optional donor contributions. The table below summarises these published figures as of our check date.

Letting donors cover the fee

Many donation forms offer a checkbox that lets the donor add an amount to cover processing costs. It is worth understanding how this differs from a surcharge. Visa defines a surcharge as an additional fee a merchant adds to a consumer's bill for using a particular form of payment. Visa's US merchant surcharge Q&A says merchants that surcharge must notify their acquirer at least 30 days in advance, limit surcharges to credit cards only, keep the amount at or below the merchant discount rate or 3%, whichever is lower, disclose it at the point of entry, the point of sale and on every receipt, and follow state laws, several of which restrict or prohibit surcharging. An optional donor contribution is different in design: the donor can decline, the gift goes through either way, and the same option is shown regardless of payment method. We did not find Visa guidance that addresses optional donor contributions specifically, so treat the checkbox as an optional contribution, not a required surcharge, and confirm with your processor how it is configured. Leave the box unchecked by default, show the exact dollar amount, and make sure the receipt reflects the total the donor actually paid. Platforms that ask donors for a tip to the platform itself, rather than to cover your fees, are a separate arrangement and should be explained clearly on the form.

Protecting recurring gifts with account updater services

Monthly giving depends on stored card details staying current, and cards are reissued for expiry, loss, fraud and upgrades. Visa Account Updater lets participating issuers submit new account numbers and expiration dates, and participating merchants, through their acquirers, query stored credentials and receive updated details where available, including account closures. Other card networks run their own updater services, but we could not verify a current public description of Mastercard's at the time of writing, so ask which networks yours covers. Both work only when the issuer participates and your processor has enabled the service, so ask whether updater is included, whether it runs automatically before each billing cycle, and whether there is a per-update fee. Pair it with a clear retry schedule and a polite email when a payment still fails, so donors can update their card themselves.

Tax receipts in the United States and Canada

Receipts are separate from payment processing but usually produced by the same donation system, so check what it generates. In the US, IRS Publication 1771 says a donor cannot claim a deduction for any single contribution of $250 or more without a contemporaneous written acknowledgment from the charity. The acknowledgment must include the organization's name, the amount of a cash contribution, a description but not the value of non-cash property, and a statement of whether goods or services were provided in return, with a good faith estimate of their value if so. Separate gifts under $250 are not added together for this rule, email acknowledgments are acceptable, and a charity must provide a written disclosure statement when a donor makes a single payment of more than $75 that is partly a contribution and partly for goods or services. In Canada, the CRA lists the information an official donation receipt from a registered charity must contain, including a statement that it is an official receipt for income tax purposes, the charity's name and address as on file with the CRA, its registration number, a unique serial number, the place of issue, the date or year the gift was received, the date issued, the donor's full name including middle initial and address, the amount of the gift, any advantage and the eligible amount, an authorized signature, and the name and website address of the CRA. Only registered charities and other qualified donees can issue official donation receipts in Canada, and a US 501(c)(3) acknowledgment does not replace a CRA receipt.

PCI DSS basics for nonprofits

The PCI Security Standards Council describes PCI DSS as baseline technical and operational requirements to protect payment account data, and it applies to all entities that store, process or transmit cardholder data. Nonprofits are not exempt. Most small organizations validate compliance with a Self-Assessment Questionnaire, and the Council notes there are several versions for different ways of accepting cards; your acquirer or the card brand determines which applies to you. The simplest way to reduce scope is to avoid handling card numbers directly: use a hosted donation page or payment fields supplied by your processor, never write card numbers on pledge cards or spreadsheets, and do not take card details by email. If volunteers take cards at events, use processor-supplied devices and remove access when the event ends.

What to compare before you choose

Start with your actual donation mix: average gift size, share of online versus in-person gifts, share of recurring gifts, and how many donations come from outside the country. Fixed per-transaction fees weigh heavily on small gifts, while percentage fees matter more on large ones. Then compare providers on total cost per donation, including platform fees, card processing, international surcharges, updater fees, chargeback fees and monthly minimums. Confirm whether charity interchange is passed through on your pricing model, what documentation the provider needs to approve nonprofit pricing, and how receipts are generated for both US and Canadian donors if you raise in both. Finally, get every rate in writing with a date, because published schedules and provider pricing change.
